Use GLM in Claude Code

Steps

1. 1
   Step 1.

   Install Claude Code (Z.ai's documented install command).

   Terminal

   Copy

   # Install Claude Code
   npm install -g @anthropic-ai/claude-code
   
   # Navigate to your project
   cd your-awesome-project
   
   # Complete
   claude

2. 2
   Step 2.

   Get a GLM Coding Plan API key. Individual Plan users create it under Personal Coding Plan > Plan Overview (https://z.ai/manage-apikey/apikey-list). Team Plan members create it under Team Coding Plan > My Plan (https://z.ai/manage-apikey/coding-plan/team/my-plan).

3. 3
   Step 3.

   Option A (automated): run Z.ai's Coding Tool Helper and follow the on-screen guidance.

   Terminal

   Copy

   npx @z_ai/coding-helper

4. 4
   Step 4.

   Option B (manual): edit ~/.claude/settings.json and add or modify these env fields, replacing your_zai_api_key. A new window is required for changes to take effect.

   JSON

   Copy

   {
           "env": {
           "ANTHROPIC_AUTH_TOKEN": "your_zai_api_key",
           "ANTHROPIC_BASE_URL": "https://api.z.ai/api/anthropic",
           "ANTHROPIC_DEFAULT_HAIKU_MODEL": "glm-5.3-flash[1m]",
           "ANTHROPIC_DEFAULT_SONNET_MODEL": "glm-5.3[1m]",
           "ANTHROPIC_DEFAULT_OPUS_MODEL": "glm-5.3[1m]",
           "CLAUDE_CODE_AUTO_COMPACT_WINDOW": "1000000",
           "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": 1,
           "API_TIMEOUT_MS": "3000000"
       }
   }

5. 5
   Step 5.

   Start Claude Code in your project. If prompted with "Do you want to use this API key," select "Yes."

   Terminal

   Copy

   cd your-project-directory
   claude

6. 6
   Step 6.

   Confirm the switch: run claude, type /status, and check that Settings source shows ~/.claude/settings.json and Model shows the GLM model. Use /effort to change thinking intensity (default max).
